To all whom it may concern:

Be it known that I, JOHN J. Toomn, a citizen of the" United States, and .a resident of the city of Chicago, and State of Illinois, have invented-certain new and useful Improvements in Impres- Devices for Type-Writers;

is a full, clear, and exact description of the same, reference. beinghadto the accompanyand'to the numbersof reference marked thereon, which form a part of] 7 this specification. Until the present time it has been very diflicult, if not-quite impossible, to correctly and easily estimate the'amount of work ac'- complished in -a-;given time by an operator at the typewriter. Slight variation in the' number of lines upon a sheet or i i-margins, may cause a'wide difference betw ii the ap-" parent amount of work accomplished in a day and the actual amount of work really turned out by theoperator. In consequence, it is very difficult to determine with exactness the difference in the quantity of work accomplished between two given operators in the same time without carefully counting Words, and even then-it never is true that the number of words may be considered as a reliable test of the amount of work accomplished by the operator in a given time. p

f' course, it is important. to know in many instances, in determining costs and efficiency with accuracy, the-real amount of work accomplished in a given time at the machine.

The object of this invention is'to afford mechanism in connection with a typewriter adapted to count or register the. number of times a letter, figure, or character is struck,

. to enable the amount ofw'ork. accomplished by the operator be absolutely determined.

It is an object of the invention to afford a construction whereby the space and shifting keys only may be actuated without registry whereby every actuation of a key or lever for a significant character or figure is correctly registered. The invention is, of course, capable of application to type registering machines of any kind. For convenience of illustration, it is shown embodied in connection with an Oliver typewriter, although, of course, (and as will hereinafter be seen) the kind, of typewriter is unimportant.

shown in the drawings: 1, indicates the typewriter as a whole, in-this instance Secured on the under s de thebase of the typewriter, is the counter2, of familiar form, arranged transversely the base, and the shaft 3, of which is engaged by a coupling 4, which engages an angular shaft 5, in the'socket thereof, as shown in Fig. 5. A casing 6, incloses said angular shaft 5, and rigidly secured in the end of the casing, is a clutch member 7', in which the coupling 4, rotates and adapted to be engaged byan inclosed clutch member 8, slidably secured on said shaft 5, and held in. engagement with the clutch member 7, by the coiled spring 9, the teeth of said clutch being so directed as to prevent reversal ofthe counter. Extending through the other end of said casing, is-a shaft 10, having a clutch member 11, thereon, which faces inwardly and engages a clutch member 12; slidably secured on the shaft 5, the teeth being directed to rotate the counter forwardly only. On the outer end 'ofthe shaft 10, is a: crank arm 13. As shown, the counter; and clutch are supported on a bracket 14, depending from the base of and affording a rigid, sup port therefor.

Secured in the end of said crank 13, is a wrist pin 15', comprising a headed screw, and secured any suitable manner upon the shifting'mechanism whereby the spacing is effected at the actuation of each key, is a reciprocating lever 16, the rear end offwhich pivotally engages the upper .end of a cam plate 17, the lower end of which is provided with 'a cam slot 18, comprising a lower sectional detail of theing motion of said cam plate is afforded bymeans of saidlever 16, the forward end of which is suitably engaged upon any part connected to be actuated by the umversal bar 20, each actuation of which in striking a key, produces a nearly vertical up an d down movement of the cam plate, as mdi- 'cated in dotted lines Fig. 3,'in Which'the mechanism is shown inverted. The upward movement actuates the crank arm 13, and shaft and consequently the counter the downward movement drawing the crank back to normal for the next actuation.

Any suitable mechanism may be connected to shift the cam plate rearwardly when the space bars or any of theshift keys are actuated. Forthis purpose a pin or stud 21,

is provided in one of the space levers 22, and a bracket 23, is secured on the'under side of the base, and projecting forwardly.

and pivotally engaged on the forward end thereof, is a downwardly and forwardly projecting hook 24, affording parallel ways, between which the pin 21, slides, as shown in Figs. 1 and 7 Pivotally secured on the lower end of said hook, 24, which, in fact, affords a crank arm on the bracket 23, is a connecting rod 25, which extends rearwardly and is engaged on a forwardly projecting lug 26, integral with the cam plate. When a shifting bar or key is struck, the downward movement of the forward end thereof swings the hook or crank rearwardly, thereby projecting the lower end of said cam plate rearwardly and bringing the wrist pin 15, into the inclined portion of the slot, as shown in Fig. 4, whereupon it is obvious that the up and down movement occasioned by the actuation of any of said space mechanisms can have no effect upon the counter whatever, inasmuch as the inclined slot in the cam plate extends nearly at a right angle with the axis of the crank.

The operation is as follows: Each actuation of a key for a significant figure produces the characteristic shifting of the actuating or supporting mechanism for the keys whatsoever key is actuated, and whatsoever typewriting machine may be employed. In the typewriter adopted for purposes of illustration, the rocker bar and attached mechanisms of an Oliver typewriter afford the means for actuating the counter,

though, of course, the particular connec tions and mechanism will vary through a considerable degree with variations in the type of machines used. However, the actua-" tion or reciprocation of any key acts through the medium of the respective key lever 16,

which bears downwardly upon the transmember is so constructed as to shift the actuating means for the counter out of actuating engagement. the cam pin is shifted on the crank arm into the inclined slot in said cam plate. In this In the present instance,-

position, the spacing bar or key may be'actuated to any desired extent, but it proves incapable of actuating the counter. When released, however, and another key is struck, the return of the space bar to normal acts to immediately shift the cam plate back to actuating position.

While I have shown a particular typewriter, it is to be understood that the use thereof is intendedto be but conventional, for it is clearly to be understood that-mechanism'embodyin my invention may be attached to typewrlters of any kind to operate substantially as hereinbeforedescribed; that is to say, to register each actuation of any of the keys or lever, whereby a significant' character of any kind is adapted to be impressed or written, and it is to be understood that I do not propose limiting the patent granted on this application, otherwise than necessitated by the prior art, but purpose claiming broadly any construction whereby the actuation of the significant characters upon a typewriter or any like machine, may be accurately registered, and the actuation of any keys or elements not for a significant character will not be registered.

I claim as my invention:

1. In a device of the class described a counter, a crank connected thereto, a cam plate adjustably connected on said crank,

and levers connected therewith, one'to cause actuation of the counter through said cam plate and crank, and the other to move said cam plate out of actuating position.

2. The combination with a typewriter of a counter, a crank connected thereto to operate the same, a cam plate connected to said crank, a lever connected to said cam plate and to the universal bar of the t pewriter actuated by each of the character eys thereof, a relatively long connecting rod connected to said cam plate and to the s ace bar of the typewriter whereby when a 0 aracter key is actuated the counter registers and when the space bar is actuated saidj long connecting rod shifts the cam plate with respect to said. crank whereby move- -ment of the camplate takes place without causing registration by said counter.

3. The combination with a typewriter of a counter mounted thereon, means connecting said counter with-the character keys of the typewriter to register each actuation of any one thereof, and mechanism connected to .the space bar of the typewriter adapted to shift said connecting means for said character keys into a position to permit actuation of the character keys-without actuation I v of said counter.

4. A registering mechanism for typewriters embracing a counter, operative connections between a part of the mechanism'of the typewriter and said counter for actuating the counter to register each and all actuations of keys for significant characters,

and a connecting rod engaged with the counter actuating means and operatively connected with the spacing mechanism and acting to' shift .the actuating means to prevent actuation of the counter when spacing or shifting keys only are actuated.

5. The combination with a typewriter of a counter mounted thereon, a crank arm for actuating the counter, a pin through saidcrank arm, a slotted plate with the slot thereof engaging over said pin to partially support said plate on said arm, a connection between said plate and the character keys of the typewriter, and means connecting said plate with the space bar mechanism of the typewriter to move said plate whereby actuation of the character keys causes said plate to slide on said pin without actuation of the counter shaft. v

6. The combination with a typewriter of a counter mounted thereon, a crank for actuating said counter, a pin on said crank, a plate having an angled slot therein with said pin engaging therethrough, means connecting the character keys of the typewriter with one end'ofsaid plate whereby when a character key is actuated said plate actuates the crank to actuate the counter, and mechanism connected with the space bar of the typewriter and with said plate whereby said plate is shifted to permit free movement of the plate on said pin relative said crank when a character key is actuated.

7. In a device of the class described a counter, a crank therefor, clutches connected between said crank and counter, a cam plate having an angled slot therein, a pin secured on said crank and slidably engaged in'said slot, an actuating lever pivoted to said plate to actuate said crank, and a lever connected.
